If you’re dealing with a silk blouse, a polyester dress, or something with a delicate synthetic blend, you need to be a gentle parent, not a drill sergeant. Synthetics melt easily, so a high-heat iron mark can be a real problem. The key here is cold, not heat.
Soak the garment in a bowl of cold water with a capful of hair conditioner for about 20 minutes. Conditioner relaxes the synthetic fibers. Then, gently rub the mark with your fingertips under cold running water. Rinse well and lay flat to dry. It’s a soothing spa treatment for your hardest-hit clothes.

The Lemon Juice Trick (For a Fresh Start)
For white cottons, like a crisp button-down shirt, lemon juice is a natural spotlight. It brightens whites and cuts through the singed layer. Drizzle a little lemon juice directly onto the mark, then sprinkle some salt on top. Let it sit in the sun for an hour—the sunlight activates the lemon juice’s bleaching power.
Rinse it out and wash as normal. You’ll get a shirt that not only looks good but smells like a summer day. It’s the kind of fix that feels like you’re playing alchemist in your own laundry room.
